CAP FOR COLLAPSI BLE TUBES Filed Feb. 19, 1932 INVENTOR WITNESSES Kennel/z Ljfayden/ v ATTORNEYS Patented June 6, 1933 UNITED STATES PATENT OFFICE GAP FOR COLLAPSIBLE TUBES Application filed February 19, 1982. Serial No 594,091.

An object of theinvention is to provide a cap for a collapsible tube having a limited movement on the tube neck and being provided with an outlet through. which the contents of the tube may be exuded.

Another object of the invention is to provide the cap with a lateral outlet whichis disposed at a side of the tube neck when the tube is sealed by the engagement of the head of the cap with the outer end of the tube neck.

Still other objects of the invention are to provide resilient means for holdin Y the cap yieldingly extended on the neck 0 the tube and to provide means for securing the cap against movement relatively to the tube.

Additional objects of the invention are to provide means to shear olf the exuded contents of the tube as desired; to provide means for measuring a definite quantity of the contents of the tube as desired; to provide means to prevent the stripping of the threads on the cap or tube and to prevent the possible cross-threading of the threads on the cap and tube; to provide means to prevent the possible loss of the compressible gasket on the cap; and to provide means to permit of the. reinpval of the cap from the tube when desire The invention also comprehends a collapsible tube having a cap for securing means for holding the cap to close the neck of the tube,-the cap having a limited movement on r the neck when freed from the said securing means to permit of the outward movement of the cap on the neck under the pressure of the contents of the tube when the tube is' Figure 2 is an enlarged fragmentary sectional View illustrating a portion of the tube with its neck and the cap secured thereto to close the outer end of the neck,

. Figure 3 is a sectional view similar to the 5 a and Figure 6 is a fragmentary sectional view illustrating another modified form of the in- 0 vention.

By referring to the drawing it will be seen that the collapsible tube 10- has a neck 11 with an external thread 12 at the inner end of the neck and an external thread 13 at the outer end of the neck. Disposed on the neck 11 there is a cap 14 having a head 15 with a gasket 16 for closing the outer end ofjthe neck, the cap 14 having at its inner end an inner thread 17 which is provided for ineshing with the thread 12 and also with the thread 13 on the neck 11. It will also be seen that the side of the cap 14 is provided with an outlet 18 which, when the thread 17 on the cap meshes with the thread 12 on the neck, will be disposed-at the outer side of the neck 11, as illustrated in Figure 2.

It will be understood that the cap 14 may be disposed on the neck 11 in the osition illustrated in Figure 4 by screwing the thread 17 on the cap 14 on the thread 13 on the neck 11, when the thread 17 on the cap 14 may engage the thread 12 on the neck 11, as may be desired.

In using the invention, the cap 14 at its thread 17 may be freed from the thread 12 on the neck 11, as illustrated in Figure 4, when the tube may be squeezed to press its contents through the neck 11 and again t the head 15 or the gasket 16 to'move the cap 14 outwardly, the outward movement of the cap 14 bein limited by the engagement of the thread fTon the cap with the thread 13 on the neck. With a further pressure against the sides of the tube, more of the contents of the tube will be exuded through the outlet 18 at the side of the ca 14, as illustrated in Figure 3. When su clent of the contents of the tube have been exuded, the cap 14 may be pressed downwardl on the neck 11, which will return some 0 the contents of the tube back through the neck 11 bv means of the downward pressure on the head 15, the remainder of the contents of the tube passing out of the outlet 18. When the cap 14 has been moved downwardly where its thread 17 is positioned for mesh-. ing with the thread 12 on the neck 11, the cap may be rotated to securethe cap to the neck by the engagement of the thread 17 with the thread 12, it being understood that with this downward movement the head 15 and the asket 16 will press against the outer end of the neck 11 to seal the latten In the form of the invention illustrated in Figure 5 of the drawing, the construction is the same as has been described with reference to the form of the invention illustrated in Figures 2, 3 and 4, but in Figure 5 the thread 12 on the neck 11 is omitted and there is an additional thread 19 at the side of the cap 14 adjacent its head 15. In this form of the invention the cap 14 is held in closed position on the neck 11 by the engagement of the thread 19 onthe cap with the thread 13 on the neck, and the outward movement of the cap 14 relatively to the neck 11 is limited by the engagement of the thread 17 on the side of the cap with the thread 13 on the neck 11. In the form of the invention illustrated in Figures 2, 3 and 4 the outward movement of the cap 14 relatively to the neck 11 is limited by the engagement of the thread 17 on the cap with the thread 13 on the neck 11. In the form of the invention illustrated in Figure 5, the cap 14 is mounted on the neck 11 by meshing the thread 17 on the cap with the thread 13 on the neck until the thread 17 is disposed below the thread 13.

In the form of the invention illustrated in Figure 6 of the drawing, the construction is the same as that illustrated in Figure 5, but in Figure 6 there is a spiral spring 20 disposed around the neck 11 and engaging the neck 11 at its thread 13, the other end of the spiral spring 20 engaging the side of f the cap at its thread 17, it being understood that this spiral spring 20 serves to move the cap 14 downwardly on the neck 11 to a position where its thread 19 is disposed for meshing with the thread 13 on the neck 11.
